Title: Heat stabilization of synthetic linear polyamides
IPC: C08K3/32
Filed: 1952-03-27
Abstract: Synthetic linear polyamides are stabilized against the degradative effects of heat and oxygen by the addition of 0.1-1 per cent. by weight of a phosphorous acid or alkali metal salt thereof and of .25-2.5 per cent. by weight of an alkali metal halide, other than a fluoride.  The stabilizing ingredients are preferably added to the amine salt prior to condensation to form the polyamide.  They may also be added during the condensation, to the molten polymer followed by homogenization by extrusion, or may be tumbled with solid polyamide particles followed by extrusion.  Sodium or potassium bromide or iodide are the preferred alkali metal halides.  The phosphorous compound catalyses the condensation reaction so that to produce a polyamide of given viscosity it will be necessary either to shorten the usual reaction period or to add acetic acid as a viscosity stabilizer.  Conventional additives, e.g. plasticizers, resin, waxes, fillers or pigments, may be blended with the stabilized polyamides.  By reason of their properties the polyamides are especially suitable for such uses as textile fabrics, electrical insulation, kinematograph film, or sausage casings.  Examples describe the addition to polyhexamethylenediammonium adipate before polyamide formation of mixtures of (1) phosphorous acid and potassium bromide, (2) phosphorous acid and potassium iodide, (3) sodium dihydrogen phosphate and potassium bromide, and (4) sodium dihydrogen phosphate and potassium iodide.  Specifications 461,236, 461,237, 557,544, 619,707 and U.S.A.  Specification 2,493,597 are referred to.

Title: Machine for producing pile fabrics
IPC: D05C15/36
Filed: 1958-03-12
Abstract: 889,973. Sewing; sewing machines. CABIN CRAFTS Inc. March 12, 1958 [Oct. 18, 1957], No. 7920/58. Class 112 A tufting machine for producing a fabric in which a patterned effect is achieved by the contrast of cut loops with uncut loops, comprises a work-table, a first looper, a second looper having a loop cutting knife, and a needle selectively engageable while the machine is running, with either one of the loopers to produce either a cut or an uncut loop. In the multiple-needle machine illustrated a first and a second looper, one at either side of each meedle are provided. The first loopers 39, carried on a bar 37 are oscillated by a rock shaft 30 driven from a main drive shaft 20. The second loopers 49 and their corresponding knives 53 are carried on bars 48, 54 respectively which are oscillated by interconnected rock shafts 40, 50 also driven from the drive shaft 20. The needles N are grouped in pairs, each pair being mounted in a tiltable holder 60 pivoted on a shaft 62 carried by the reciprocating needle bar 12. The holder 60 carries a laterally extending arm 63 and is spring urged into a position where the needles are vertical. As the needle bar reciprocates, driven from the shaft 20, the vertical needles co-operate with the first loopers 39 to produce uncut loops in the material C as it is fed across the table. Needle tilting levers 70 having arms 71, 73 are pivoted to the frame of the machine adjacent to the paths of the holders as they reciprocate with the needle bar. When a tilt lever is actuated by a pneumatic piston and cylinder arrangement 76 the arm 71 projects into the path of the arm 63 to pivot the holder 60 as the needle bar descends, thus deflecting the needles from the vertical to cooperate with the second looper and its associated knife to produce cut loops. The pistons are operated from solenoid valves 77 selectively energized through circuits including fingers trailing on the surface of a rotating drum, on which surface a pattern is formed in which electrically conductive areas correspond to the areas of the fabric where cut loops are to appear. Specification 889,974 is referred to.

Title: Circuit arrangement for transmitting signal messages over telephone lines
IPC: H04M11/00
Filed: 1928-03-15
Abstract: 294,196. Siemens & Halske Akt.-Ges. July 20, 1927, [Convention date]. Fire and police alarm systems. -One and the same conductor of a telephone subscriber's loop is employed. for transmitting fire and police alarms from the substation to the exchange and standard-time signals from the exchange to the substation. In one system Fig. 1, ordinary conversations are established over automatic switches VW, GW, &o., which are set into operation when a calling subscriber Tn lifts his receiver by the completion of a circuit for the upper winding of relay R over a choking coil Dr<2> and earth at the substation. Normally a circuit exists over contact 3b1, relay A1(i) operated contacts 4a1, Dr5, b, Dr3, F, and over this circuit the substation battery is charged by the exchange battery. Standard-time signals are transmitted by a clock-controlled contact 8u which opens the above circuit so that an impulse is sent to clocks Ur1, relay A1 being held during the impulse over winding (iii). If a burglary or fire occurs, the throwing over of contact 5m1 or 6m2 unlocks relay A1 which on releasing connects relay S in series with interrupter LU or SU so that the operator's lamp L is flashed at a correspondingly slow or fast rate. The fact that the substation clocks are no longer controlled from the exchange warns the subscriber of danger. If the substation loop becomes short-circuited relay Al is shortcircuited by relay R(i) and relay S is connected up to light lamp L continuously. If conductor b becomes earthed, the increase of current through relay A1 operates a further armature 5a1 to again light lamp L continuously. In a second arrangement, Fig. 2, standard-time signals are transmitted by master-clock contacts u1, u2, which alternately connect opposite poles of battery to the lead b2. A differential relay A3 having one winding in series with lead b2 and the other winding in parallel therewith does not respond to the time signals. If, however, contacts m3 or m4 are thrown over, the balance of relav A3 is upset so that the relay responds and operates a drop-indicator. The exchange attendant on seeing this throws over key Ta to connect up a relay G which under the control of interrupter SU1 or LU1 flashes lamp Lg at a charactertistic frequency. If the line a2, b2, becomes earthed or short-circuited, relay A3 is again unbalanced and lamp Lg glows continuously. Relay A3 may be replaced by two relays which control one another. A differential galvanscope T serves for regulating the relay A3.

Title: An improved rail waggon retarder
Inventor: WALKER GEORGE WILLIAM
IPC: B61K7/08
Filed: 1958-03-13
Abstract: 908,056. Railway track braking apparatus. PLOWRIGHT BROS. Ltd. March 13, 1959 [March 13, 1958], No. 8038/58. Class 103 (1). A rail waggon retarder has a brake member 1a, Figs. 2, 4, securely mounted on a support 3 which slidably supports brake member 1, the support 3 being slidable normal to the track, actuating means 16 acting to move the members 1, la relative to each other, and resilient biasing means 10 acting between support 3 and member la, the resilient means and actuating means acting in mutual opposition. A bellcrank 14, pivoted at 13 to support 3, is rotated counterclockwise by actuator 16 to engage a fulcrum 20, pivoted at 21 to a boss 19 of beam 1, to slide support 3 and member 1 relative to each other to apply the shoes 2 to a vehicle wheel. A spring 10 releases the brake by rotating bellcrank 14 clockwise out of contact with fulcrum 20. A duplicate bell-crank 14<SP>1</SP> moves the opposite ends of the beams 1, 1a. The retarder comprises a series of beams pivoted together as at 9, and the fulcrums 21, slidable longitudinally by a linkage, Fig. 4 (not shown), are adjustable relative to bell-crank pivots 13 according to the weight and speed of the vehicle and so vary the braking pressure. The weight of a vehicle on a rail 32, Fig. 7, rotates a frame 29 against spring 34, to rotate a bellcrank 39, Fig. 8, to move the fulcrums 20 through a linkage, Fig. 9 (not shown), the linkage being locked in its adjusted position by a pawl. A skid 46, Figs. 10, 13, when depressed by a vehicle moves a piston 57 in a liquid-filled cylinder 50; should the piston be moved quickly, by a fast vehicle, then a washer 60 closes large ports 59 and since restricted flow only can take place through small ports 58, the cylinder 50 is moved against spring 56 to operate linkage 54, 44, 25 to further adjust fulcrums 20. A pawl 55 locking lever 54 in its new position. A slow vehicle moves piston 57 slowly and fluid flows through ports 58, 59, cylinder 50 remaining stationary. The pawls are released from levers 43, 54 by a linkage operated by a further skid being depressed by the vehicle. The small ports 59 may be replaced by an external connection including a control valve by-passing piston 57. The retarder in Figs. 16, 17 is applied by actuator 16 rotating bell-cranks 70 to engage fixed fulcrums 71 on beam 1, the beam and support moving as before. An abutment 73 limits inward movement of the beams 1, 1a and a bolt 75 in bracket 74 limits outward movement and adjusts the gap between the beams. The retarder is released by spring 81 acting between a bracket 84 on support 3 and a collar 83 on rod 80 fixed to beam 1, and also by a spring 77 acting between a fixed abutment 76 and a collar 82 on a rod 78 fixed to support 3. In Figs. 18 19 (not shown), the retarder is applied by springs and released by a fluidpressure actuator.

Title: Improvements in or relating to braking means for railway wagons and the like adaptedto be controlled according to varying conditions of loading
IPC: B60T8/18
Filed: 1952-03-31
Abstract: 706,235. Fluid pressure railway brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. March 31, 1952 [April 10, 1951], No. 8112/52. Class 103(1) A variable load braking apparatus for vacuum operated braking systems for railway vehicles comprises a variable leverage mechanism which, upon an increase in pressure in the train pipe, brings about a local admission of air to a brake operating cylinder at a pressure determined by the load carried by the vehicle. The valve mechanism comprises a casing 1 subdivided internally into three main compartments by resilient diaphragms 2 and 3 acting upon a lever 12 to control the operation of a spring controlled valve 10 which governs the entry of atmospheric air through port 11. Compartment 4 is in open communication with the train pipe through passage 5. Compartment 6 is in open communication with the upper chamber of the brake cylinder. Compartment 7 is in open communication through passage 8 with the lower chamber of the brake cylinder and also communicates through a non-return valve 9 with the train pipe compartment 4. Control lever 12 is provided with a fulcrum 13 mounted on a sliding member 14 engaging an arm 18 mounted on a short shaft 19 which extends through a packed gland in the wall of the casing 1. Damping arrangements prevent transient vibrations of the vehicle spring deflection from being transmitted to the mechanism for adjusting the fulcrum 13 so that this adjustment is controlled solely by the vehicle load. The shaft 19 is coupled to one end of a lever 22 by a screw threaded arm 23, the opposite end of the lever 22 being secured to a dashpot device 26 secured to the casing 1. One end of an arm 29 is pivotally mounted on a support 30 secured to a casing 1, the arm 29 being coupled at an intermediate point to a spring strut device 31. The opposite end of the arm 29 is pivotally connected to an adjustable head 32 arranged to rest on the bogie of the vehicle, a compression spring 33 being interposed between the head 32 and an abutment 34, secured to the body of the vehicle. By this means only sustained variations of load, affect the position of the fulcrum 13 along lever 12. A relief valve 43 is provided, which when opened establishes communication between the upper and lower brake cylinder chambers, thereby reducing the degree of brake application. The spring-loaded relief valve 43 controls communication between a compartment 44 connected by passage 45 with the passage 8 leading to the lower brake cylinder chamber and is operated through a flexible diaphragm separating compartments 6 and 44 by the lever 49 driven by a cam 57 fixed to a shaft 19, when a sustained variation of load takes place. Preferably the vehicle is provided with two brake cylinders; one for effecting braking in accordance with the tare weight, the other being provided with the invention to effect braking in accordance with the loading of the vehicle.

Title: Improvements in wringers
IPC: D06F45/04
Filed: 1938-03-16
Abstract: 498,786. Wringers ; machinery safety devices. LOVELL MANUFACTURING CO. March 16, 1938, No. 8114. Convention date, March 17, 1937. [Class 138 (ii)] [Also in Group XXIV] A wringer is provided with a quickacting release device for the pressure means and with a pressure re-setting means, the release device taking the pressure after it has been applied by the re-setting means, thereby relieving the latter. A pin 20 extending between the limbs of one of the side stiles 2 passes through cam slots 18 in the limbs of a bifurcated latch member 15 pivoted at 16 in the top bar 12. The bridge 17 of the latch member is engaged by a lip 23 on the release member 21 which is pivoted at 22 in the top bar and may be provided with a spring 21a. On depressing the release member counterclockwise, the lip 23 frees the latch member, and the pin 20 acting on the inclined portion 19 of the cam slot rotates the latch member so that the pin now registers with the long portion 18 of the slot, thereby permitting the latch to use and take with it the top bar and so relieve the pressure. A lever 24 is pivoted at 25 to the top bar and is provided with a pin 31 which engages a slot 28, 29 in a link 26 pivoted at 27 to the side stile. On raising the lever 24 to the position shown, the pin travels along the slot 28 until it is beneath the portion 29, whereupon the link 26 drops by gravity assisted by a spring 30a to lock the members 24, 26 together. The lever is now rotated to apply the pressure until the lip 23 engages the bridge 17 of the latch 15 by which time the spring 30a will pass off the projection 30 of the link 26 and the latter will be retarded in its movement and break the operative connection between the pin 31 and slot 29, the pin now riding freely in the slot 28. In a modification, the link 34 in the form of a bail is pivoted at 35 to the operating lever 32 and a cross - member 34a thereon extends through a strap 36 secured to the face of a side stile. The upper end of the strap forms a shoulder 37 to serve as a pivot for the link 34 during operation of the lever 32.
